CVE-2021-20277

A flaw was found in Samba's libldb. Multiple, consecutive leading spaces in an LDAP attribute can lead to an out-of-bounds memory write, leading to a crash of the LDAP server process handling the request. The highest threat from this vulnerability is to system availability...

CVE-2020-27840

A flaw was found in samba. Spaces used in a string around a domain name DN, while supposed to be ignored, can cause invalid DN strings with spaces to instead write a zero-byte into out-of-bounds memory, resulting in a crash. The highest threat from this vulnerability is to system availability...

samba -- Multiple Vulnerabilities

The Samba Team reports: CVE-2020-27840: An anonymous attacker can crash the Samba AD DC LDAP server by sending easily crafted DNs as part of a bind request. More serious heap corruption is likely also possible. CVE-2021-20277: User-controlled LDAP filter strings against the AD DC LDAP server may...

Heap corruption via crafted DN strings

Description A DN may be represented in string form with arbitrary amounts of space around the component values. These spaces are supposed to be ignored, but invalid DNs strings with spaces may instead cause a zero byte to be written into out-of-bounds memory. An LDAP bind request can send a strin...

Out of bounds read in AD DC LDAP server

Description A string in an LDAP attribute that contains multiple consecutive leading spaces can lead to a memmove of out of bounds memory in ldbhandlerfold. ldbhandlerfold is used by case insensitive strings - that is most string attributes - in Active Directory. As the search expression is...

The vulnerability of the Kerberos protocol implementation in Samba’s network interaction software packages arises from a lack of privilege control mechanisms and access management tools. This allows attackers to induce service failures.
